2
3 Changes between versions 0.4b38 and 0.4b39 (released ???????????????)
4 =====================================================================
5
6 1. The newly added dump_on_cd_3 example was buggy, replace it
7 with an updated version from Andrew Basterfield
8 <bob@cemetery.homeunix.org>.
9
10 Changes between versions 0.4b37 and 0.4b38 (released January 7, 2005)
11 =====================================================================
12
13 1. Fix a couple of troff syntax bugs in the man pages.
14 Thanks to Eric Raymond <esr@thyrsus.com> for the patch.
15
16 2. Made restore use either libncurses or libtermcap, depending
17 on which one is available at configure time.
18
19 3. Fixed restore negative size display bug when comparing a
20 dump containing files over 2GB. Thanks to Steve Bonds
21 <sbonds@users.sourceforge.net> for the bug report.
22
23 4. Do not save directory entries to non-dumped inodes
24 (excluded from dump). This will eliminate the 'missing
25 file' warnings when doing 'restore -C'.
26
27 5. Fix dump crash when backuping a huge (2TB) filesystem,
28 due to a bogus calculation on the inode map size.
29 Thanks to Kevin B. Haines <K.B.Haines@rl.ac.uk> for
30 submitting the bug and testing the fix.
31
32 6. Fix a problem in restore where the final \0 in the symbolic
33 link names could have been lost, generating corrupt filenames.
34 Thanks to Kyle Wilson <kyle.wilson@amd.com> for reporting the
35 bug.
36
37 7. Implemented a hash list for the directory names in restore.
38 The linear list used before caused problems in interactive
39 restores when dealing with directories having thousands of
40 entries. Thanks to Brian Ristuccia <bristuccia@starentnetworks.com>
41 for reporting the bug.
42
43 8. Improved restore -C, this time including the directory
44 attributes into the comparision.
45
46 9. Made restore understand tapes containing EA/ACLs (which will
47 be dumped by the next version of dump). In this version
48 extended attributes on the tape are ignored, for full EA/ACL
49 support wait for the next version or try the experimental EA
50 patch.
51
52 Changes between versions 0.4b36 and 0.4b37 (released July 7, 2004)
53 ==================================================================
54
55 1. Added the --enable-staticz configure option which enables
56 dump and restore to be linked with static versions of
57 libz and libbz2 (and dynamic versions of all other libraries).
58 This will make Debian users happy, because libz and libbz2
59 were the only needed libraries living in /usr, all the
60 others live in /lib. In case of system emergency, it is
61 better not to have to rely on an extra filesystem.
62 Thanks to Bdale Garbee <bdale@gag.com> for the suggestion.
63
64 2. Fix compilation on (at least the Linux Debian port to) AMD64.
65 (<ext2fs/ext2_types.h> defines some types (__s64 and __u64)
66 that are also defined by <linux/types.h> (<asm/types.h>) and
67 they conflict).
68
69 3. Make dump's reading of the dumpdates file a bit more robust,
70 preventing dump from crashing when the dumpdates file has
71 been modified by hand.
72
73 4. Fixed some offset calculations in dump code which could
74 lead to "bread lseek errors" on large filesystems. Thanks
75 to Bruce Lowekamp <lowekamp@users.sourceforge.net> for
76 reporting this bug and debugging the issue.
77
78 5. Made dump use the blkid library when searching for devices
79 by label or uuid instead of dump's own routines.
80
81 6. Corrected a bug in dump where a wrong LABEL=... line in
82 /etc/fstab could prevent dump from dumping unrelated
83 filesystems. Thanks to Bruce Lowekamp
84 <lowekamp@users.sourceforge.net> for reporting the bug.
85
86 Changes between versions 0.4b35 and 0.4b36 (released April 21, 2004)
87 ====================================================================
88
89 1. Fixed dump compilation with old gcc versions. Thanks to
90 Mike Castle <dalgoda@users.sourceforge.net> for the patch.
91
92 2. Fixed some warnings (howmany, roundup, powerof2 redefined)
93 when compiling against a recent glibc version.
94
95 3. Fixed a bug in restore preventing the read of a dump tape
96 written with Solaris 7 ufsdump. Thanks to Patrick Higgins
97 <phiggins@transzap.com> for reporting the bug and providing
98 the test case.
99
100 4. Changed dump to enable the creation of volumes of different
101 sizes in a single run (make -B accept a list of values).
102 Patch contributed by Florian Zumbiehl <florz@gmx.de>.
103
104 5. Use the glibc provided minor() and major() macros instead
105 of our own bitmask implementation. This should be safe for
106 when the major/minor namespace will migrate to 32 bits.
107 Thanks to Zhang Jun <zhangjun@nanjing-fnst.com> for reporting
108 the bug.
109
110 6. Made explicit in the dump man page that dump will not create
111 a remote file, it will only write to an already existing one.
112
113 7. Another try at making size estimates better again.
114
115 8. Put back the inconditional running of the end-of-tape
116 script which was changed in 0.434 to be run only when -M
117 or multiple -f were NOT specified. Some users rely on this
118 feature even when it is combined with -M/-f.
119
120 9. Fixed restore when restoring huge backups (where rstdir...
121 temporary files are over 2GB). Thanks to
122 Raphael Jaffey <rjaffey@artic.edu> for reporting this,
123 debugging the issue and making the patch.
124
125 10. Made restore understand FreeBSD UFS2 tapes. Thanks to
126 David <vrtin@users.sourceforge.net> for submitting the bug
127 and providing a test case.
128
129 11. Made dump work with an arbitrary integer level (no more 10
130 levels only limitation). Thanks to Matthew
131 <msvincen@midway.uchicago.edu> for the patch.
132
133 Changes between versions 0.4b34 and 0.4b35 (released December 21, 2003)
134 =======================================================================
135
136 1. Added a note in the dump man page saying that the default
137 blocksize can be 32 if -d is used with a high density argument.
138 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
139 for the patch.
140
141 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
142 LDFLAGS environment variables. Thanks to Arcady Genkin
143 <antipode@users.sourceforge.net> for reporting the bug.
144
145 3. Made -e/-E options of dump accept an unlimited number of inodes
146 to be excluded, rather than a hardcoded maximum. Thanks to
147 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
148
149 4. Updated the autoconf system to 2.50. Forced the -D_BSD_SOURCE
150 and -D_USE_BSD_SIGNAL defines in configure in order to solve
151 64bit build problems because quad_t is redifined with a
152 different signature. Thanks to Mike Harris <mharris@redhat.com>
153 for reporting this bug.
154
155 5. Made restore build on Solaris, making possible to
156 restore Linux's "enhanced" tapes. Thanks to Uwe Gohlke
157 <uwe@ugsoft.de> for the patch.
158
159 6. Made an extension in the dump tape format capable of saving
160 MacOSX specific inode extensions. Uwe Gohlke <uwe@ugsoft.de>
161 wrote the extension and contributed the restore code back
162 into this codebase. The same extension mechanism will be
163 used in the future to save ACLs...
164
165 7. Made rmt work correctly with regard to QFA and local/remote
166 files and tapes. The remote access will however work only
167 when the dump provided rmt version is used. If you want to
168 use another rmt server, please do not use the QFA feature.
169 Thanks to Uwe Gohlke <uwe@ugsoft.de> for the patch.
170
171 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
172 ====================================================================
173
174 1. Fixed the INSTALL file to reflect the actual install paths.
175 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
176 reporting the bug.
177
178 2. Fixed the configure script to only check for headers presence
179 instead of trying to compile them. This should fix issues
180 with old build environments. Thanks to Kari Lempiainen
181 <kari@funky.pp.fi> for reporting the bug.
182
183 3. Fixed restore to correctly ignore sockets when comparing
184 a dump (as socket cannot be properly restored anyway). Thanks
185 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
186
187 4. Fixed restore to correctly access the archive file (-A argument)
188 even when using a remote tape. Thanks to Fabrice Bellet
189 <fabrice@bellet.info> for reporting the bug.
190
191 5. Fixed (again) handling of long (largefile) seeks in rmt.
192 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
193 the bug.
194
195 6. Fixed restore corner case when dealing with large block sizes
196 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
197 <fabrice@bellet.info> for reporting the bug.
198
199 7. Fixed a bug preventing dump to access a filesystem having
200 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
201 for reporting the bug.
202
203 8. Made dump store dump dates using explicit timezones, fixing a
204 problem with incremental dumps if the timezone is modified
205 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
206 the bug report and the patch.
207
208 9. Fixed a bug encountered when dumping individual files (not full
209 filesystems or directories) and dangling symbolic links happen
210 to be in the list of files. For as far as dump is concerned,
211 dangling symbolic links are allowed, and are dumped as is.
212 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
213 bug and providing the fix.
214
215 10. Fixed open and creation modes and permissions for QFA and
216 table-of-contents files in dump and restore. Thanks to
217 Philippe Troin <phil@fifi.org> for the patch.
218
219 11. Fixed the archive file descriptor handling enabling it to be 0.
220 This can happen in some cases when shell redirections are used.
221 Thanks to Philippe Troin <phil@fifi.org> for the patch.
222
223 12. Delayed the opening of archive file until after suid had been
224 dropped (fixing a possible security issue if dump is suid).
225 Thanks to Philippe Troin <phil@fifi.org> for the patch.
226
227 13. Fixed the 'S' command handling in the rmt client part.
228 Thanks to Philippe Troin <phil@fifi.org> for the patch.
229
230 14. Modified the end-of-tape script handling to print out statistics
231 (and stop the timer) before launching the eot script. Also, the eot
232 script does not get run anymore when using -M (which makes sense) or
233 when multiple tapes are listed on the command line
234 (-f tape0,tape1,tapen) (which also makes sense).
235 Thanks to Philippe Troin <phil@fifi.org> for the patch.
236
237 15. Relicensed dump/restore under the 'revised' BSD license, as per
238 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
239
240 16. Added LZO compression to dump. This new compression method has
241 the advantage of being super fast, thus not killing tape streaming
242 on slow machines. Thanks to Helmut Jarausch
243 <jarausch@igpm.rwth-aachen.de> for the patch and to
244 Markus Oberhumer <markus@oberhumer.com> for giving special permission
245 to include his miniLZO project (GPL licensed) in dump/restore.
246
247 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
248 <ant@notatla.demon.co.uk> for reporting the bugs.
249
250 18. Added a special rmt version which can do encryption when writing
251 to tape. Read examples/encrypted_rmt/README for details on
252 how to enable and configure it. Thanks to Ken Lalonde
253 <ken@globalremit.com> for the patch.
254
255 19. Made dump work with 2.5 kernel end of tape early warning semantics.
256 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
257
258 20. Fixed a bug which caused dump -w|-W not to work anymore, because
259 the fs_freq and fs_passno fields in /etc/mtab are always set
260 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
261 reporting the bug.
262
263 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
264 =======================================================================
265
266 1. Added a note in the restore man page clarifying the question
267 'set the permissions on the current directory ?' asked by
268 restore at the end of treatment in -i and -x modes.
269
270 2. Fixed the endianess issues when reading compressed tapes.
271 Thanks to Dark Force <daq4th@users.sourceforge.net> for
272 reporting this bug and providing test cases.
273
274 3. Fixed the "ACL won't be dumped" warning message (which showed
275 an extra, unrelated error message). Thanks to Dragan Krnic
276 <dkrnic@lycos.com> for reporting this bug.
277
278 4. Made dump look first into /etc/mtab, then into /etc/fstab
279 when searching for filesystem paths. Also fixed some problems
280 caused by binding mounts or multiple block device mounts.
281 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
282 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
283 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
284 and #160305, Sourceforge bugs #618699 and #679832).
285
286 5. Made dump's -I option accept the value '0' meaning all the
287 read errors will be ignored. This can be useful when running
288 dump from unattended sessions (like cron jobs). Thanks to
289 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
290
291 6. Fixed the output of dump to indicate 'blocks' instead of
292 'tape blocks' in the various messages (blocks are always
293 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
294 made it clearly print the current blocksize at the start of
295 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
296 the suggestions.
297
298 7. Made rmt understand long (largefiles) seeks.
299
300 8. Fixed build with very old versions of libext2fs, where
301 EXT2_FT_* constants were undefined.
302
303 9. Made dump accept the dumpdates path on the command line
304 (-D file option) instead of using only the hardcoded one.
305 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
306 suggestion.
307
308 10. Enabled rmt, LFS, readline, QFA options by default in
309 ./configure. Updated the configure process (new versions
310 of config.guess, config.sub etc).
311
312 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
313 =======================================================================
314
315 1. Changed dump to use fcntl(F_SETLK) style locking instead
316 of flock() when locking the dumpdates file. With the old
317 locking scheme, a local user having read rights on the
318 dumpdates file could be able to do a Denial of Service attack
319 on dump. In order to lock the dumpdates file with the new
320 scheme, the user would need to have write access on the file.
321 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
322 reporting the bug (originally a bugtraq post).
323
324 2. Fixed interactive 'ls' which caused spurious errors warnings
325 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
326 <jorgen_ostling@users.sourceforge.net> for reporting this
327 bug.
328
329 3. Fixed dump's estimate when dealing with sparse inodes.
330
331 4. Modified dump to allow setting a blocksize bigger than 32kB
332 (raised the limit to 1024kB), because newer hardware needs
333 this for proper operation. Thanks to Dirk Traenapp
334 <dtraenapp@users.sourceforge.net> for reporting this.
335
336 5. Fixed a bug causing Dump to stop and report an error if an
337 inode number in the exclude file was followed by some amount
338 of whitespace. Thanks to Jeffrey Sofferin
339 <sofferin@users.sourceforge.net> for reporting this bug.
340
341 6. Fixed a bug which caused restore, in some particular cases,
342 to ask some 'scary' questions and leave a bunch of RSTTMP
343 directories behind when restoring incremental tapes. Thanks
344 to Philippe Troin <phil@fifi.org> for reporting this bug and
345 providing the test cases.
346
347 7. Changed the wording when inodes are excluded from dump:
348 replaced 'Added inode 7 to exclude list' with
349 'Excluding inode 7 (resize inode) from dump', as suggested
350 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
351
352 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
353 ===================================================================
354
355 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
356 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
357 <eros@lamel.bo.cnr.it> for reporting the bug.
358
359 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
360 ===================================================================
361
362 1. Made dump print out the ext2 logical block number in case of a read
363 error, which can be given as an argument to debugfs' ncheck command,
364 in order to find out the affected inode. Added note about this
365 usage in dump's man page.
366
367 2. Fixed a problem in restore when reading tapes written on big
368 endian machines with very old versions of dump. The patch was
369 contributed by George Helffrich <george@geology.bristol.ac.uk>.
370
371 3. Fixed the tape length calculation when using large tapes
372 and compression. Thanks to Georg Lippold
373 <g_lippold@sourceforge.net> for reporting the bug.
374
375 4. Added a new set of examples in dump_on_cd_2 directory, based
376 on dump_on_cd examples but somewhat enhanced, supporting DVD
377 media, and localized in english and german. Thanks to
378 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
379
380 5. Made dump save 32 bit UID/GID. Internally, this was achieved
381 by switching from the old BSD inode format to the new BSD
382 inode format, which means that the tape format was changed.
383 However, since all restore versions out there should
384 transparently support both inode formats, the change should
385 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
386 reporting the bug.
387
388 6. Fixed a lot of warnings in the code shown when compiling
389 with 'gcc -W'. Thanks to Matthias Andree
390 <matthias.andree@stud.uni-dortmund.de> for reporting this.
391
392 7. Fixed a small markup bug in the dump man page. Thanks to
393 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
394 patch.
395
396 8. Rewrote entirely the man pages using the tmac.an macro
397 package (Linux man page format) instead of the original BSD
398 format. They should be now cleaner and easier to modify.
399
400 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
401 ==================================================================
402
403 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
404 non Linux clients were misinterpreted. The description of the problem
405 (incompatible numbering in Linux mtio opcodes) is documented at
406 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
407 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
408 providing an excellent, cross-platform replacement for rmt in his
409 star package.
410
411 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
412 which caused restore to fail when the inode maps were not entirely
413 contained on the first volume (when using really small volumes or
414 when dumping a huge number of inodes).
415
416 3. Fixed a problem in dump, where files in subdirectories of directories
417 that have the nodump flag set (or being excluded with -e/-E) were
418 sometimes incorrectly dumped (instead of being excluded). The original
419 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
420 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
421 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
422 help testing the patch.
423
424 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
425 which makes one able to pipe the output of dump, by the net, to
426 a remote CD-burner server.
427
428 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
429 and use GNU's symbolic syntax over rmt instead of numerical values
430 to assure multiple platform compatibility.
431
432 6. Documented the -d option in restore.
433
434 7. Added a -v (verbose) mode to dump. For now it just prints the number
435 of the inode being dumped, but this could evolve in future versions
436 to include interesting debugging output.
437
438 8. Added a -o flag to restore, which automatically restores the current
439 directory permissions in -i or -x mode, without asking the operator
440 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
441 and Peter Samuel <peters@e-smith.com>.
442
443 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
444 ====================================================================
445
446 1. Fixed a bug in the QFA feature which could have caused
447 a bad tape positionning on restore (causing extra delays in
448 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
449
450 2. Added a small note in the dump man page specifying that
451 there should be no white space between the option letter and
452 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
453
454 3. Made restore work with older versions of the readline library,
455 by checking in configure for several extended symbols. Restore
456 can now be compiled with a readline as old as the 2.0 release
457 (though it may be a good idea to upgrade it to a more recent
458 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
459 reporting the build failures.
460
461 4. Fixed a performance problem with the QFA file creation in
462 dump, which made unnecessary seeks on the tape slowing down
463 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
464 reporting this issue.
465
466 5. Removed the inclusion of some kernel headers in the dump
467 source, which prevented the compile in some kernel/glibc
468 headers/architecture combination. Thanks to Bdale Garbee
469 <bdale@gag.com> for reporting the bug.
470
471 6. Added the appropriate error message when dump fails to
472 open the output file for writing. Thanks to Amith Varghese
473 <amithv@yahoo.com> for reporting this bug.
474
475 7. Made restore able to understand large Solaris ufsdump tapes
476 (containing inodes bigger than 4194304). Sun have introduced
477 an "extension" to the dump tape format when dealing with
478 those inodes, which was uncorrectly handled by Linux restore.
479 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
480 providing a test case.
481
482 8. Added the -m parameter to dump which optimises the output for
483 inodes having been changed but not modified since the last dump
484 ('changed' and 'modified' have the meaning defined in stat(2)).
485 For those inodes, dump will save only the metadata, instead of
486 saving the entire inode contents. Inodes which are either
487 directories or have been modified since the last dump are saved
488 in a regular way. Uses of this flag must be consistent, meaning
489 that either every dump in an incremental dump set have the flag,
490 or no one has it.
491
492 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
493 =======================================================================
494
495 1. Fixed behaviour of dump when exceeding resource limits
496 (SIGXFSZ treatment).
497
498 2. Added the -L flag to restore to allow the user to specify a
499 maximal allowed number of miscompares when using restore
500 with the -C option to check the backup.
501
502 3. Detailed the manual entry for the -N option of restore.
503
504 4. Added the -a flag to restore to make able doing unattended
505 restores in -i or -x mode (automatically walks through the
506 multiple dump volumes).
507
508 5. Extended the QFA mode to work with local files and/or
509 remote tapes and files. This way, restore can know in advance
510 the tape number and the offset for the inodes to extract and
511 can minimize the extraction time by seeking directly to the
512 good tape/offset.
513
514 6. Added the -A <archive> option to both dump and restore,
515 which makes dump to archive a dump table-of-contents in
516 the specified file to be used by restore to determine
517 whether a file is in the dump file that is being restored.
518 (the archive file syntax is also compatible with the
519 Solaris ufsdump generated one).
520
521 7. Small fix in restore making it able to read some (broken ?)
522 Solaris ufsdump tapes.
523
524 8. Fixed dump to correctly recognise the root filesystem when using
525 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
526 for reporting this bug.
527
528 9. Added the -P <file> option to restore to create a
529 Quick File Access file from an already made dump. Patch
530 contributed by Uwe Gohlke <uwe@ugsoft.de>.
531
532 10. Made restore compile and run on Solaris, making it a
533 possible replacement for the standard ufsrestore. Port was
534 contributed by Uwe Gohlke <uwe@ugsoft.de>.
535
536 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
537 =====================================================================
538
539 1. Added a set of backup scripts from Eugenio Diaz
540 <getnito@yahoo.com> in the examples section. It features
541 automatic (cron based) full and incremental dumping of
542 several filesystems on a separate filesystem.
543
544 2. Fixed a off-by-one miscalculation which disabled dumping
545 a one letter subdirectory. Thanks to Chris Siebenmann
546 <cks@utcc.utoronto.ca> for reporting the bug.
547
548 3. Fixed several restore bugs occuring when trying to
549 restore some missing files on the tape. Thanks to Chris
550 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
551
552 4. Fixed --with-ldopts configure argument passing, installing from
553 a separate object directory, makefile cleanups contributed
554 by <splite@purdue.edu>.
555
556 5. Fix a bug which could caused, in some conditions, the highest
557 number inode of a filesystem, to not be dumped. Many thanks
558 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
559 chase this bug.
560
561 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
562 =======================================================================
563
564 1. Added a mini howto from Patrick Walsh in the examples
565 directory.
566
567 2. Minor man pages syntax corrections. Thanks to
568 Chris Danis <screechco@home.com> for reporting the bugs.
569
570 3. Added a script from David B. Peterson <dave@toppledwagon.com>
571 to the examples section. It features dumping several
572 filesystems to a remote tape drive upon ssh.
573
574 4. Added a patch provided by Richard Jones <rich@annexia.org>
575 which allows BRADEMAX (number of read errors tolerated by
576 dump) to be adjusted using the -I option.
577
578 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
579 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
580 patch.
581
582 6. Add the -l option to restore to specify if, when doing a
583 remote restore, the file used to access the backup is a
584 regular file (the defaults being a tape drive). Restore needs
585 to know this information when reading a remote compressed
586 dump. Previously, this information was autodetected, but
587 the autodetection code fails (with ioctl: Inappropriate ioctl
588 for device) when using a non Linux remote box. Thanks to
589 many users and especially to Eros Albertazzi
590 <eros@lamel.bo.cnr.it> for reporting this.
591
592 7. Found a workaroung for the dump deadlock problem (3 childs
593 stuck in pause(), father in read()). The workaround seems
594 to work for me and several beta-testers. If it doesn't work
595 for you, please report back.
596
597 8. Updated the RPM spec file (BuildPrereq, URL etc).
598
599 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
600 ========================================================================
601
602 1. Fixed the permissions of a newly created QFA file by dump.
603
604 2. Cleaned up the source of dump (the external variables
605 definition was a complete mess, making possible to have
606 objects overlap).
607
608 3. Fixed restore to use the full tape volume path when doing
609 a compare (since it changes the working directory to the
610 filesystem being compared in the process).
611
612 4. Added the -q option to dump which makes dump abort
613 whenever it needs operator attention. It should be
614 easier to use dump in scripts with this option.
615
616 5. Detect the use of incompatible options to dump and
617 refuse them (like -a and -B options together).
618
619 6. Added bzip2 compression to dump/restore (use option -j level
620 to select it). Note that you will need a restore version
621 >= 0.4b24 in order to restore a bzip2 compressed dump.
622 The same warning as for the zlib compression applies:
623 the tape format of a bzip2 dump is not compatible with the
624 original BSD tape format.
625
626 7. Fixed a overflow problem in dump corrupting the dump when
627 very large files were encountered. Thanks to Vladimir Nadvornik
628 for the bug report.
629
630 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
631 kernel buffer/page cache before starting the dump, helping
632 a bit those who use dump on mounted filesystems. Thanks to
633 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
634 for this suggestion.
635
636 9. Updated the RPM spec file following the RedHat changes
637 (dynamically linked binaries now in /usr/sbin etc).
638
639 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
640 which enables restore to recognise multi volume compressed dumps
641 done on CD. Included his scripts for dump (which pipe the dump
642 output directly into cdrecord) and restore. There is now
643 possible to to backups to CD on the fly!
644
645 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
646 ===================================================================
647
648 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
649 Marcus Meissner (Caldera International Security Dept.).
650
651 2. Implement the Sun rmt extended protocol. Patch submitted
652 by Ian Gordon <iangordon@users.sourceforge.net>.
653
654 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
655 the linux kernel header. This ensures that dump always has the
656 latest version of this file. Patch submitted by
657 Andreas Dilger <adilger@turbolinux.com>.
658
659 4. Report any filesystem present in either /etc/fstab with a
660 positive passno or /etc/dumpdates in dump -w output.
661 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
662
663 5. Fixed the looping problem in dump introduced in the
664 previous version.
665
666 6. Changed the -B option of dump to limit the size of
667 _compressed_ output per volume if compression is on.
668 Patch contributed by Helmut Jarausch
669 <jarausch@igpm.rwth-aachen.de>. Note however that, since
670 it is impossible to predict the size of the compressed
671 data before doing the compression, the -B limit is a bit
672 conservative.
673
674 7. Fixed a bug in reading the operator typed file/tape path for
675 the next volume in restore.
676
677 8. Implemented a "-F script" option to restore which permits the
678 user to specify a script which will be launched at the
679 beginning of each tape, useful for automatic programming of
680 tape changers for example. See the restore man page for the
681 script parameters and return codes.
682
683 9. Small fix for the QFA routines provided by Uwe Gohlke
684 <uwe@ugsoft.de>, and some recommendations for QFA uses in
685 the man pages.
686
687 10. Fixed the multivolume restoring where making a mistake
688 to the 'Mount next tape' prompt caused several blocks to
689 be lost.
690
691 11. Enhanced the -e option of dump to take as a parameter a
692 comma separated list of inode numbers.
693
694 12. Added the -E option to dump which specify a file containing
695 inode numbers to exclude from the dump.
696
697 13. Fixed the compressed multi-volume dump + restore.
698
699 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
700 ==================================================================
701
702 1. Made dump report the number of blocks dumped per volume.
703 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
704
705 2. Fix a bug in dump where waiting too much at the 'change volumes'
706 question caused the volume to be rewritten. Thanks to
707 Graham Reed <greed@users.sourceforge.net> for reporting the
708 bug and providing a patch.
709
710 3. Added a compression option to dump, contributed by Jerry
711 Peters <gapeters@worldnet.att.net>.
712
713 WARNING: the compression works only on files/pipes and
714 drives supporting variable block size.
715
716 WARNING2: tapes created using the compression feature are
717 incompatible with the standard dump tape format, and a
718 version of restore >= 0.4b22 will be needed for extraction.
719
720 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
721 architectures. Thanks to Paul Slootman <paul@debian.org> for
722 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
723 it upstream.
724
725 5. Many cleanups (CPP defines, const char warnings, check of
726 ext2fs COMPAT flags, time_t cleanups, added libext2 version
727 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
728
729 6. Made --prefix option work in configure. All the install path
730 are now based on the configure parameters.
731
732 7. Added the Quick File Access mode in dump/restore, contributed
733 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
734 a file tape position for each inode, and this file is used by
735 restore (if called with parameter Q and the filename)
736 to directly position the tape at the file restore is currently
737 working on. This saves hours when restoring single files from
738 large backups, saves the tapes and the drive's head. Use
739 --enable-qfa option of configure to compile in the QFA support.
740
741 8. Added the possibility to dump several files and directories
742 in a single invocation of dump. Thanks to Uwe Gohlke
743 <uwe@ugsoft.de> for implementing this option.
744
745 9. Fixed the dumping and restoring of files with holes
746 (files ending with holes didn't get dumped or restored
747 correctly).
748
749 10. Fixed a socket descriptor leak in dump, which leaved opened
750 3 file descriptors per dump process (and there is one dump
751 process per tape).
752
753 11. Fixed dump large file system support, by explicit use of
754 open64/lseek64/etc functions (explicit use needed because
755 e2fsprogs libraries don't behave well when compiled with
756 FILE_OFFSET_BITS=64).
757
758 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
759 ======================================================================
760
761 1. Fixed some bugs in the dump -w|-W logic introduced by
762 the previous version. Thanks to Andreas Dilger
763 <adilger@turbolinux.com> for his help on this one.
764
765 2. Fixed again a compilation problem when using old e2fs
766 headers (filesystem label related). Thanks to many users
767 who reported this stupid error.
768
769 3. Fixed a build problem on old lib5 based systems dealing with
770 _PATH_MNTTAB being undefined. Thanks to John Adams
771 <johna@onevista.com> for reporting the bug.
772
773 4. Improved the error detection in restore when creating
774 the temporary files in TMPDIR. Now restore will corectly
775 report a 'no space left on device' error instead of
776 strange errors which could imply an archive corruption.
777 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
778 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
779
780 5. Added the throughput information in dump's progression
781 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
782 for the patch.
783
784 6. Use libext2fs's inode scanning routines, which are particularly
785 robust when dealing with errors (especially when having some
786 bad blocks on the filesystem). Many thanks to Colin
787 <colin@horizon.com> for reporting the bug, investigating
788 the issues, finding a workaround, writing the patch and
789 fully testing it... (of course, if this patch will break
790 anything, he is to blame for :-)).
791
792 7. Made dump and restore LFS aware. Dump can dump a filesystem
793 containing large files, generate a large file on output and
794 restore can restore them. This feature is not enabled by
795 default, use --enable-largefile option of configure to enable
796 it (you need to have a LFS aware glibc though). Thanks to
797 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
798 and to Theodore T'so <tytso@valinux.com> for his always
799 useful thoughts.
800
801 8. Made dump ask upon a tape write error if it should rewrite
802 the current volume (assume this is a bad tape) or if it should
803 assume an end-of-tape condition (useful for tape drives which
804 behaves badly at the end of the tape). Thanks to Andreas
805 Dilger <adilger@turbolinux.com> for the suggestion.
806
807 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
808 =======================================================================
809
810 1. Fixed a small compilation problem due to a change
811 in the definintion of the struct sigaction in
812 glibc 2.0 / libc5. Thanks to Gunther Schlegel
813 <schlegel@riege.de> for reporting the bug and to
814 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
815 a fix.
816
817 2. Modified the label and uuid analysis in order to be
818 self-contained (independant of kernel/libc headers). This
819 should fix the compile with older kernel/libc headers and
820 will preserve the functionality. Thanks to Bernhard Erdmann
821 <bernhard.erdmann@gmx.de> for reporting the bug.
822
823 3. The 'exclude inode' option, if applied to a directory
824 inode, excludes now correctly all the leaves of this
825 directory. Thanks to John R. Dennison
826 <gerdesas@users.sourceforge.net> for reporting the bug.
827
828 4. Fixed the '-e' option to disable the possibility
829 to exclude the root inode (which causes the dumps to
830 be unreadable by restore). Prevented array overflow
831 when multiple -e options are used.
832
833 5. Fixed dump to correctly interpret a filesystem argument
834 which is a mountpoint and it is not an absolute path
835 (as specified in the fstab). Thanks to Bernhard R. Erdmann
836 <be@berdmann.de> for reporting the bug.
837
838 6. Made dump able to backup files larger than 2 GB. Note that
839 dump still doesn't cope with files larger than 4 GB.
840
841 7. Restore the real uid and gid before invoking an external
842 RSH program (big hole when dump or restore is suid root!).
843
844 8. Get the values for the default tape device and the location
845 of fstab file from the system headers. Thanks to
846 Andreas Dilger <adilger@turbolinux.com> for the patch.
847
848 9. Made dump -w|-W report all recognized filesystems
849 present in either /etc/fstab or /etc/dumpdates, and present
850 the list in the same order as in fstab file. Thanks
851 to Andreas Dilger <adilger@turbolinux.com> for the patch.
852
853 10. Made dump's -a (automatic end of tape detection) the
854 default. Specifying one of -B, -c, -d or -s options will
855 override the EOM detection. Thanks to Andreas Dilger
856 <adilger@turbolinux.com> for the patch.
857
858 11. Save the ext2 filesystem label into the dump volume label.
859 Specifying a volume label on the command line (-L option)
860 will override this feature. Thanks to Andreas Dilger
861 <adilger@turbolinux.com> for the patch.
862
863 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
864 =====================================================================
865
866 1. Fixed the signal handling in dump (which I broke in 0.4b17)
867 which was causing several strange dump failures (dump
868 hanged or segmentation faults etc).
869
870 2. Specified the default blocksize in the dump man page.
871
872 3. Changed two info messages of restore to be written on stdout
873 instead of stderr in order to leave stderr only for errors
874 or warnings. Thanks to Stephen Atwell
875 <satwell@urbana.css.mot.com> for the suggestion.
876
877 4. Corrected an off by one calculation which prevented
878 dumping a directory having a 1 character name length.
879 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
880 for reporting the bug.
881
882 5. Reinforce dump in order to allow only level 0 and no
883 -u option when dumping a subdirectory, and document
884 this in the man page. Thanks to Bernhard Erdmann
885 <bernhard.erdmann@gmx.de> for reporting the bug.
886
887 6. Fixed a small harmless bug in restore which caused
888 in some conditions hard links to be restored several
889 times (therefore generation some warning messages).
890 Thanks to Kenneth Porter <shiva@well.com> for
891 reporting the bug.
892
893 7. Updated the RPM spec file to the latest RedHat version,
894 providing FHS packaging and other cosmetic changes.
895 You will need RPM version >= 3.0.5 in order to build the RPM.
896
897 8. Updated the configure script to check for libtermcap
898 before checking for libreadline, because we need this
899 library in order to compile the readline support.
900
901 9. Made dump understand the LABEL= and UUID= notation
902 both in /etc/fstab and on the command line. Note that
903 you will need the /proc filesystem in order to use
904 these notations. Thanks to Erik Troan <ewt@redhat.com>
905 for providing the patch.
906
907 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
908 ===================================================================
909
910 1. Fixed a potential buffer overflow in restore. Thanks
911 to Stan Bubrouski <satan@fastdial.net> for reporting
912 the bug.
913
914 2. Fixed a readline-related bug which prevented
915 'cat DUMPFILE | restore -i -f -' from working. Thanks
916 to Charles Karney <karney@users.sourceforge.net>
917 for the bug report.
918
919 3. Changed a few "panic" into "exit", causing restore to
920 be more stable against some attacks (like the last one
921 reported on Bugtraq, although the last version of restore
922 was not vulnerable - just dumped core). Thanks to
923 Andreas Hasenack <andreas@conectiva.com.br> for reporting
924 the bugs to me.
925
926 4. Removed the suid-root bit on dump and restore in the
927 default build (and generated RPMs). It should be safer
928 now. Users who need the suid-root capabilities in order
929 to make network backups should read first the man page
930 of dump and enable the suid bit manually.
931
932 5. Added -ltermcap to the compile parameters for restore
933 when using readline support, in order to make the compile
934 process work on some systems (SuSE ?). Thanks to
935 Patrik Schindler <poc@pocnet.net> for reporting the bug.
936
937 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
938 ====================================================================
939
940 1. The -F script is called now *only* at the end of a tape,
941 not at the end of the dump. Thanks to Christian Haul
942 <haul@informatik.tu-darmstadt.de> for the bug report.
943
944 Normally, the device name and the current volume number
945 are passed on the command line of the script. However,
946 if you want the old style script (with no arguments
947 passed on the command line), you can enable it in
948 configure with the --enable-oldstylefscript.
949
950 2. Use posix signal handling to preserve dump functionality
951 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
952 the patch.
953
954 3. Made the exit code of restore in case of a 'C'ompare
955 command reflect the result of the compare. An exit status
956 of 0 means the dump archive is correct, 1 means tape errors,
957 2 means that some files were modified. Thanks to Kenneth Porter
958 <shiva@well.com> for the suggestion.
959
960 4. Made (finally) quotes work in interactive restore.
961
962 5. Small fixes in order to allow dump to compile with a
963 really old e2fsprogs version. Thanks to Ian Zimmerman
964 <itz@speakeasy.org> for the bug report.
965
966 6. Add GNU readline capabilities to interactive restore.
967 Use configure's --enable-readline flag to enable this feature.
968 Thanks to Patrik Schindler <poc@pocnet.net> for the
969 suggestion.
970
971 7. Do the compare on the fly in restore 'C' mode (this will
972 allow not to exhaust the available /tmp space when
973 ccmparing large files). Thanks to Kenneth Porter
974 <shiva@well.com> for the suggestion.
975
976 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
977 ====================================================================
978
979 1. Fixed some several duplicate 'DUMP: DUMP:' in the
980 output of dump.
981
982 2. Corrected the estimation of blocks to dump. Note that
983 this is still wrong for large directory inodes, due
984 to the size of a BSD directory entry on the tape
985 (estimation is based on the size of the ext2 directory,
986 which is smaller because it doesn't contain the null
987 character at the end).
988
989 3. Made dump report the total number of MB written to
990 tape at the end of run. Thanks to W. Reilly Cooley
991 <wcooley@nakedape.cc> for the patch.
992
993 4. Added the -X option to restore giving the possibility
994 to read the names of the files to be extracted/listed
995 from a text file (in addition of the command line).
996 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
997 patch.
998
999 5. Added the device name and the current volume number
1000 as arguments to the end of tape script (dump -F option).
1001
1002 6. Made the multi-volume dump work again (after having
1003 broken it in 0.4b15).
1004
1005 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
1006 ===================================================================
1007
1008 1. Added a prompt command in interactive restore mode. Thanks
1009 to Andreas Dilger <adilger@home.com> for the patch.
1010
1011 2. Fixed a buffer overflow problem in dump (caused by
1012 not checking the size of the filesystem parameter).
1013 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
1014 reporting this on Bugtraq (and to several dump users
1015 who forwarded me his mail).
1016
1017 3. Added the '-F script' option to dump in order to
1018 launch a script at the end of each tape (to be used
1019 with a tape changer, or to notify the sysadmin by
1020 pager etc.).
1021
1022 4. Fixed a bug in restore compare code caused by the changes
1023 I made in 0.4b14.
1024
1025 5. Fixed the treatment of options using the old BSD syntax
1026 in both dump and restore.
1027
1028 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
1029 =======================================================================
1030
1031 1. Fixed a bug in dump which may have caused invalid deleted
1032 directories to be dumped out if they were deleted after the
1033 mapping pass. This could occure on active filesystem and lead
1034 to heap corruption (causing dump malfunction in many possible ways).
1035 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
1036 bug and submitting the patch.
1037
1038 2. Fixed the handling of the filesystem parameter in dump. A
1039 '/mnt/disk' parameter caused the disk contents to be dumped,
1040 but a '/mnt/disk/' parameter caused the mountpoint directory
1041 to be dumped (generally an empty directory).
1042
1043 3. Improved the output of dump in order to tell which directory
1044 it is currently dumping (when dumping a subtree).
1045
1046 4. Added the '-e' exclude inode option to dump. Thanks to
1047 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
1048
1049 5. Added a REPORTING-BUGS file in order to provide a guide
1050 on how to correctly report a bug in dump/restore.
1051
1052 6. Fixed a restore problem when restoring a hard link to an inode
1053 having the immutable or append-only attribute set. Thanks to
1054 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
1055
1056 7. Fixed a compatibility problem between dumps made on little
1057 endian machines (the format was correct) and big endian
1058 machines (the format was incorrect). This fix break the
1059 compatibility with the older dumps made on big endian
1060 machines (sparc, m86k, ppc etc). For the first time in
1061 linux dump's history (I believe), the dumps made by *BSD,
1062 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
1063 so interchangeable. Thanks to Rob Cermak
1064 <cermak@ahab.rutgers.edu> for submitting the bug and
1065 helping me test the fix.
1066
1067 8. Fixed the way dump reports the remaining percent/time, if
1068 the number of blocks actually dumped exceeds the estimated
1069 number of blocks. Thanks to Jean-Paul van der Jagt
1070 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
1071
1072 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
1073 ======================================================================
1074
1075 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
1076 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
1077
1078 2. Removed the requirement to build the RPM as root from the
1079 spec file. Thanks to Christian Weisgerber
1080 <naddy@mips.rhein-neckar.de> for submitting this.
1081
1082 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
1083 causing dump to block when dumping really huge filesystems.
1084 Many thanks to Patrik Schindler <poc@pocnet.net> for
1085 helping me find this bug.
1086
1087 4. Fixed the treatment for an interrupt signal when dump access
1088 the remote tape through RSH. Thanks to Christian Weisgerber
1089 <naddy@mips.rhein-neckar.de> for providing the patch.
1090
1091 5. Fixed a bug which was causing dump/restore to display
1092 garbage characters instead of the remote host name.
1093
1094 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
1095 =====================================================================
1096
1097 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
1098 <kukuk@suse.de> for submitting the patch.
1099
1100 2. Fix for the exit code when using the size estimate option of
1101 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
1102 submitting the patch.
1103
1104 3. Handle EINTR in atomical reads/writes in dump, which was causing
1105 dump to fail on some systems. Thanks to Eric Jergensen
1106 <eric@dvns.com> for reporting the bug and submitting the patch.
1107
1108 4. Handle more than 16 characters for the device names in dumpdates.
1109 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
1110 tracking down the problem and proposing the solution.
1111
1112 5. Fixed a bug in dump which prevented the creation of the
1113 dumpdates file when doing a 0-level dump without already
1114 having a dumpdates file. Thanks to Patrik Schindler
1115 <poc@pocnet.net> for reporting the bug.
1116
1117 6. Changed the way dump 'S' flag reports the size estimate
1118 from number of blocks into bytes (making it compatible
1119 with the Solaris version, and simplifying things for
1120 amanda users). Thanks to Jason L Tibbitts III
1121 <tibbs@math.uh.edu> for reporting the bug.
1122
1123 7. Fixed a compatibility problem in linux/alpha dump tape format.
1124 Now the linux/alpha dump are (again) compatible with the
1125 other dump formats. But this breaks compatibility with
1126 older dumps made on alpha. Thanks to Mike Tibor
1127 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
1128
1129 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
1130 ======================================================================
1131
1132 1. Added a '--enable-kerberos' to configure.
1133
1134 2. Added a 'S' option to dump which determines the amount of space
1135 that is needed to perform the dump without actually doing it, similar
1136 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
1137 <cermak@ahab.rutgers.edu>.
1138
1139 3. Added a 'M' multi-volume option to dump and restore which enables
1140 dumping to multiple files (useful when dumping to an ext2
1141 partition to make several dump files in order to bypass the 2GB
1142 file size limitation). The 'f' argument is treated as a prefix and
1143 the output files will be named <prefix>001, <prefix>002 etc. With
1144 the 'M' flag, restore automatically selects the right file without
1145 asking to enter a new tape each time.
1146
1147 4. Fixed a memory leak which was causing dump to grow very big
1148 (270MB when dumping a 10GB filesystem...). Thanks to Jason
1149 Fearon <jasonf@netrider.org.au> for reporting the bug.
1150
1151 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1152 ======================================================================
1153
1154 1. Make configure test if the system glob routines support
1155 extended syntax (ALTDIRFUNC). If not, use the internal glob
1156 routines instead of system ones. Thanks to Bernhard Sadlowski
1157 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1158 and helping me resolve this and other minor libc5 compiling
1159 glitches.
1160
1161 2. Fix a problem when dumping a ext2fs with the 'filetype'
1162 feature enabled. Thanks to Patrick J. LoPresti
1163 <patl@cag.lcs.mit.edu> for reporting the bug and to
1164 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1165
1166 3. Made the nodump flag work on directories. A directory which
1167 has the nodump flag gets never dumped, regardless of its
1168 contents.
1169
1170 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1171 which allows dump on an active ext3 filesystem. However, this
1172 is a "quick and dirty" patch which enables backup of an ext3
1173 filesystem through the ext2 compatibility (by ignoring the
1174 NEEDS_RECOVERY bit). The journal file is not recognized and
1175 it is dumped (it should not).
1176
1177 5. Test the superblock compatibility flags when dumping, in order
1178 to be sure that we know how to deal with specific features.
1179
1180 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1181 ====================================================================
1182
1183 1. Use lchown instead of chown, fixing a possible security problem
1184 when restoring symlinks (a malicious user could use this
1185 to deliberately corrupt the ownership of important system files).
1186 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1187 this and providing the patch.
1188
1189 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1190 ====================================================================
1191
1192 1. Put dump sources under CVS, added Id tags in all files so
1193 one can use 'ident' on binary files.
1194
1195 2. Added the dump/restore version in the usage text so one can
1196 easily verify the version he is using.
1197
1198 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1199 a va_start/va_end problem on linux-ppc (always call va_start
1200 va_end in pairs each time we use a vararg function).
1201
1202 4. Added again the DT_* constants because old libc does not
1203 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1204 for submitting the bug report.
1205
1206 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1207 this should enable dumping big (huge) filesystems.
1208
1209 6. Added the RSH environment variable in order to be able to
1210 use a rsh replacement like ssh when doing remote backups (and
1211 bypass the security limitations of rcmd). Now you can do remote
1212 backups without being root (or making dump setuid root).
1213
1214 7. Modified again the way dumpdates works. For incremental dumps,
1215 we need to read dumpdates even if we are not using 'u' option.
1216 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1217 this should work.
1218
1219 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1220 ===================================================================
1221
1222 1. Removed the 'k' flag from the restore 'about' text if kerberos
1223 was not compiled in.
1224
1225 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1226 to them (fsetflags takes a char*, setflags an open fd!).
1227
1228 3. (f)setflags is called only if the flags aren't empty. If the
1229 file is a special file, a warning is printed, because changing
1230 flags implies opening the device. Normally, a special file
1231 should not have any flag... (Debian bug #29775, patch provided
1232 by Abhijit Dasgupta <abhijit@ans.net>).
1233
1234 4. Made possible to dump a file system not mentioned in /etc/fstab.
1235 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1236
1237 5. Changed the default behaviour to not create dumpdates
1238 unless 'u' option is specified. Removed the old "debian-patch"
1239 which provided the same thing. (Debian bug #38136, #33818).
1240
1241 6. Removed all those dump*announce, since they were getting old...
1242
1243 7. Added warning messages if dumpdates does not exist and
1244 when an inferior level dump does not exist (except for a level 0
1245 dump).
1246
1247 8. Debugged the glob calls in interactive mode: restore used a
1248 dirent struct which was different from the /usr/include/dirent.h
1249 one (this used to work, is it a glibc2 change?), so none of the
1250 compat glob (which used /usr/include/dirent.h) or the system glob
1251 worked. Restore use now the system dirent (and the system
1252 DT_* constants), which are compatible with BSD ones.
1253
1254 9. Added a configure flag (--with-dumpdatespath) to specify
1255 the location of dumpdates file. By default, it is
1256 /etc/dumpdates.
1257
1258 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1259 included the current date/version in man pages.
1260
1261 11. Corrected the estimation of remaining time when
1262 the operator doesn't change the tapes quickly enough. This
1263 was an old bug, I thought I corrected it, and discovered
1264 that in fact it was corrected in two different places, so
1265 the results canceled each other...
1266
1267 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1268 ===================================================================
1269
1270 1. Integrated multiple patches from RedHat, Debian and SuSE:
1271
1272 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1273 isn't specified.
1274 - several fixes in the man pages.
1275 - update the default tape device to /dev/st0.
1276 - many updates for Linux Alpha (byte ordering, size_t etc).
1277 - buffer overruns.
1278 - use environment variable for TMPDIR (instead of /tmp).
1279 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1280 - workaround egcs bug (RedHat bugs #4281 and #2989).
1281 - wire $(OPT) throughout Makefile's.
1282
1283 2. Upgrade the dump revision to 1, making possible to dump filesystems
1284 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1285
1286 3. Fix some compile warnings, prototype all functions.
1287
1288 4. Use glibc err/glob instead of internal compatibility
1289 routines (only if available).
1290
1291 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1292 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1293
1294 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1295 ======================================================================
1296
1297 1. Integrated the changes from FreeBSD-3.1-RELEASE
1298 (mostly bug fixes, buffer overruns, dump has now an "automatic
1299 tape length calculation" flag, dump/restore can use kerberos now
1300 (this is NOT tested), use environment variables for TAPE and
1301 RMT etc.).
1302
1303 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1304
1305 3. Corrected a bug in restore when using 'C' option with multi-volumes
1306 tapes (files splited accros two tapes give "size changed" errors
1307 when comparing).
1308
1309 4. Corrected the long standing bug when dumping multiple tapes.
1310 This works for me, needs further testing.
1311
1312 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1313 ====================================================================
1314
1315 1. Dump now runs correctly on kernels 2.1.x
1316 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1317
1318 Changes between versions 0.4b2 and 0.4b3
1319 ========================================
1320
1321 1. Use realpath() if available
1322
1323 2. Report statistics
1324
1325 Changes between versions 0.4b1 and 0.4b2
1326 ========================================
1327
1328 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1329 the patch)
1330
1331 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1332
1333 3. Fixed configure.in to correctly handle --enable-rmt
1334
1335 Changes between versions 0.3 and 0.4b1
1336 ======================================
1337
1338 1. Integrated the changes from 4.4BSD-Lite2
1339
1340 2. Integrated the patches from Debian and Red Hat
1341
1342 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1343
1344 4. Changed dump to use the Ext2fs library to get block addresses. This
1345 should solve the endianness problem on SparcLinux.
1346
1347 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1348 distribution's one) to use autoconf
1349
1350 6. Fixed a few minor bugs
1351
1352 Changes between versions 0.2e and 0.2f
1353 ======================================
1354
1355 1. Added the creation of named pipes (fifos) in restore.
1356
1357 2. Added the -N flag in the restore manual page.
1358
1359 3. Added the file kernel.patch which contains the llseek() optimization
1360 patch for 1.2.x kernels.
1361
1362 4. Fixed a bug in the restoration of symbolic links: owner and group were
1363 not restored.
1364
1365 5. Integrated some changes from FreeBSD 2.2.
1366
1367 6. Added a call to ftruncate() after restoring each file to restore
1368 correctly files ending by a hole.
1369
1370 Changes between versions 0.2d and 0.2e
1371 ======================================
1372
1373 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1374 with owner = root (0) and group = root/wheel/whatever (0).
1375
1376 Changes between versions 0.2c and 0.2d
1377 ======================================
1378
1379 1. Dump is now able to backup 2GB+ filesystems.
1380
1381 2. Dump and restore can now be linked as static binaries.
1382
1383 Changes between versions 0.2b and 0.2c
1384 ======================================
1385
1386 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1387
1388 Changes between versions 0.2a and 0.2b
1389 ======================================
1390
1391 1. Really fixed the bug that I should have corrected in 0.2a.
1392
1393 2. Enabled optimization again.
1394
1395 Changes between versions 0.2 and 0.2a
1396 =====================================
1397
1398 1. Disabled the optimization during compilation.
1399
1400 Changes between versions 0.1 and 0.2
1401 ====================================
1402
1403 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1404 the fs_type field (actually, I modified the file fstab.c to make it
1405 use the mntent functions).
1406
1407 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1408 made by dump should be readable by the BSD restore and backups made
1409 by the BSD dump should be readable by restore. Unfortunately, this
1410 means that the dump format has changed between version 0.1 and version
1411 0.2 :-(
1412
1413 3. Dump is now able to backup a subtree, it is no longer limited to whole
1414 filesystems like the BSD version.
1415
1416 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1417 than 2 GB.
1418
1419 Changes between versions 0.0 and 0.1
1420 ====================================
1421
1422 1. Now create links rdump and rrestore during the `make install' step.
1423
1424 2. Linux port specific bugs added to the manual pages
1425
1426 3. Incorrect estimation of the number of tapes blocks fixed when doing
1427 incremental backups.
1428
1429 4. Better ls-like format in restore in interactive mode.
